Abstract
The invention belongs to the technical field of heat exchangers, and particularly relates to an air conditioner indoor unit and a heat exchanger thereof. The technical problem that the amount of refrigerant in the lower portion of a heat exchanger is smaller than that of refrigerant in an upper portion of the heat exchanger in the prior art so that the heat exchanging capability of the lower portion is weaker than that of the upper portion is solved. Under the working condition of heating, refrigerant enters a flute-shaped tube from the lower end of a flow guiding tube, enters various branches from top to bottom and enters corresponding flow paths. Under the condition that the amount of the refrigerant is insufficient, a large amount of high-temperature gaseous refrigerant can enter flow paths positioned on the lower portion of the heat exchanger, and the heat exchanging effect of the flow paths on the lower portion of the heat exchanger can be improved. By the heat exchanger, the problems that airflow of an indoor unit of a floor type air conditioner with a through-flow fan is distributed unevenly and the airflow of the lower portion of the air conditioner is too high are solved, the temperature of discharged air of the upper portion of the air conditioner indoor unit and the temperature of discharged air of the lower portion of the air conditioner indoor unit can be even owing to the heat exchanger, and the comfort level of a user is improved. Moreover, the problems that a flute-shaped tube in the prior art is bent so as to change the direction of a flow path, but the flute-shaped tube is difficult to bend and occupies large space after being bent are solved.
